Specification of Letters Patent; 7 Patented Oct. 14,

Application filed February 20, 1919. Serial No. 278.208;

To all whom it may concern Be it known that 1, JAMES A. GRUNDY, citizenof the United States, residing in the city of Philadelphia, State ofPennsylvania, have invented certain new and useful Improvements inJacquard-Card-Punching Devices, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part of this specification.

The invention has for its purpose, the perforating or punching ofjacquard cards, used in Jacquard loomsand similar devices,

and more particularly, has for its purpose,

the simultaneous punching of two or more cards which are to besubsequently coordinately used upon such devices, whereby a plurality ofpatterns to be woven may be simultaneously controlled and so combined asto considerably shorten the length of the usually endless chain ofcards.

It is the present practice in perforating jacquard cards to utilizefinger controlled punching heads with twelve and occasionally sixteenpunching plungers. Inasmuch as all of the finger operated control keysmust be held in locking position by the fingers during the time of theperforating or punching operation of the machine, it is impossible insuch structure to remove any of the fingers from certainof the operatedkeys in order to operate certain others with out the first-mentionedkeys returningto ineffective position, and consequently, it has beendiflicult heretofore to' operate more than twelve keys by the fingercontrol and holding method, while extraordinary iSkll'l is requiredinunanipulating sixteen keys.

The invention herein disclosed, therefore,

has for its principal o'bjectstlie overcoming of the above difficultiesand also for. the permitting of the use of an indefinitely large numberof punches either in a singlesystem or. in multiple, whereby the fingerkeys may be operated and when so ope-rated, will remain in punch-lockingposition. when the fingers are removed-from said keysto other keys untilthe operatoroperates the perforating mechanism, and subsequently themeans for positively returning the keys to ineffective or inoperativeposition.

In attaining these objects generally under the name ofRoyal piano Ipreferably utilize existing perforating means-known;

heads, andadapting the same, in a manner hereinafter more fullydisclosed, to the partlcular' purposes indicated.

' Another "object is to enable; one to utilize a'finger keyboard fromwhich tocontrolthe locking rods rather than directly moving the rodsinto locking position as in the old form" of device. i V

A further obj ect is to employ an electrical system-controlled fro-1nsaid keyboard and effective to' influence the selected-and propermovement of the locking pins by means of electromagnets connected inthecircuits of the system.

further object is also to provide certain vis ble signals, as. coloredlights, operable to indicate the particular circuit or circuits, and pinor pins controlled from the finger operated keyboard.

A further object is to provide a special form of circuit closing. meansfor so controlling the circuits that the' chance of interference of thecircuits of one set of the perforating devices with another set isabsolutely avoided.

A further object is 'to' provide means whereby the circuit closingdevices may be all returned to theneutrazl or the inoperative positionby the operation of a single finger operated means i I 'A still furtherobject is to providem'eans whereby in the event that it is desired torepeat a design or pattern in any set of the perforating devices, thecircuit closing means of the other circuits may be. broken or returnedto neutral or inoperative position, While those to be repeated remain inoperative connection for the next punching operation, thereby avoidingthe necessity of again j mampulatlng corresponding keys therefor uponthe keyboard.

A still further object is to so construct the devicethat the switches orthe circuits may be controlled in a converse manner, that is,

all the circuits may be initiallyc'losedand the pattern or design to beproduced 'efi'ected bythe opening of certain-of the circuits by thereturning of the corresponding keys on the key-board to neutralposition.

A still further object is to employ supple Cir ticular design effect orpattern, such as a twill, a satin, a honeycomb, or the like.

A still furtherobject is to so arrange and connect the circuitcontrolled means that a composite pattern or design may be produced fromthe combined operation of both the supplemental and individual selectiveswitch means.

Another and still further object is to enable me to perforate correlatedcards in multiple, the particular form of means chosen for illustrationhere operating upon two cards of which one contains the pattern of theother with an additional pattern. 7

These and other objects and advantages flowing from this invention willbe disclosed in the following specification and appended claims. I

For the purpose of c'arrying'out the invention, one formof device orembodiment of the invention is more fully described in the specificationand illustrated in the drawings. I

Referring now to the drawings, in which the same reference charactersindicate the correspondingelements in the various views:

Figure 1 is a plan view, in diagrammatic form, of a pair of punchingheads with the connected electromagnets and of the finger keyboard, aswell as the wiring diagram forming the first and second circuits of eachset; v Y

Fig. 2 is an end view, partially in section of the keyboard and circuitclosing mechanism.

Fig. 3 is a view partly in transverse section of the perforating device;

Fig. 4 is a fragmentary illustration of the usual form ofchart used inconnection with the finger keyboard for obtaining the patterns punchedin the cards;

Fig. 5 is a broken plan sectional view of the keyboard showing moreparticularly the suplementary circuit closing means.

Fig. 6 isa transverse section of the means shown in Fig. 5. I

Figs. 7 and 8 show two of the contact bars that may be used in thesupplementary circuit closing means shown in Figs. 5 and 6 as well asthat shown in Figs. 9 and 10.

Fig. 9 is a view similar to Fig. 5 of a modification of the means showntherein.

Fig. 10 is a transverse section of the means shown in Fig. 9; and,

Figs. 11, 12 and 13 are fragmentary portions of design charts showingexamples of the type of pattern that may be obtained with thesupplementary circuit closing means shown in Figs. 5, 6, 9 and 10.

The mechanism employed comprises two punch heads, 1 and 2, usuallytermed Royal piano heads, which are each provided with sixteenperforations, 3 and 4, and in which are adapted to verticallyreciprocate the perforating or punching plungers 5 and 6.

The heads are also provided with lateral perforations 7, 8, 9 and 10through which are adapted to reciprocate the locking rods 11, 12, 13 and14 connected at an end thereof to the armatures 15, 16, 17 and 18 of theelectromagnets 19, 20, 21 and 22, suitably mounted upon brackets 23secured to the undersurface of the table 24. WVhen any of theelectromagnets are energized, the armatures are caused to swing aboutthe pivots 25 toward the cores 26 of said electroniagnets andreciprocate the locking rods through their corresponding lateralperforations, provided in the heads 1 and 2, t interpose the ends 27,28, 29 and thereof immedi-' ately above the upper ends 31 of thepunching plungers, the coil springs 27, 28, 29 and 30 operating toreturn said locking rods to ineffective or inoperative positions whenthe electromagnets are deenergized. Any tendency of the punchingplungers t subsequently move upwardly is thus impeded by said ends 31.Consequently, upon a downward movement of the heads 1 or 2, and thepunching plungers, toward'a stationary body, the lower end 32 of a punching plunger, will contact therewith and the locked punches operated toperforate the body while the other punches will be caused to retreatthrough and in the perforations 3 or. 4. This body is usually in theform of a sheet of card-board, 33 or 34 which is--intermittently fedbetween the die plates 35 and 36, through the holes 37 and 38 of whichthe ends of the punching plungers are adapted to be guided during thepunching operation.

The heads 1 and 2 are also provided with larger perforations 39 and 40in which are adapted to reciprocate punching plungers 41 and 42 for thepurpose of perforating peg holes in the cards at suitable places. Theseplungers are also controlled by locking rods 43 and 44 controlled byelectromagnets 45 and 46 mounted upon the lower side of the table" ina'manner similar to the electromagnets hereinbefore described. The ends47 of these punching plungers are also guided through the holes 48 inthe die plate 35 during their punching operation.

Upon the table 24 is provided a finger operated keyboard or switchboardwhich is utilized for the purpose of controlling the locking rodsreferred to above. Inasmuch as there are sixteen pattern punchingplungers in each head, two sets of finger keys, 49 and 50, of whichthere are sixteen in each set, the keys 50 of one set being operated forthe control of the punching plungers in the head 1 and the finger keys49 of the other set being operated for the purpose of con trolling thepunching plungers in both heads 1 and 2.

The finger keys are rigidly mounted upon the vertically reciprocabletems 51 and 52,

passing through the table'and pivotallysecured to the ends 53 and 54: ofthe cross-bars 55, which are fulcrumed upon a shaft 56 To the-ends ofthe cross bars are pivotally connected the links 57 and 58 in connectionwith contact plungers 59 and 60, the ends of which are adapted when recirocated to contact with and close the gaps 'etween the spring contacts'61 and 62, suitably mounted upon and insulated from the table or base,

for the purpose of closing an electrical circuit including said springcontacts.

At the end of the switchboard is also provided the addition finger keys63 and 6a connected to the cross-rod '65, circuit closing meansidentically the same as that shown in Fig. r This additional circuitclosing means is utilized for the purpose of controlling the circuits tothe electro-magnets 15 and 4:6 and the large punches 4:1 and 42 for thepeg holes referred to hereinbefore.

Located above to overlie the cross bars .55 and 65 are the horizontalbars 66 and 67 "secured to the vertical rods 68 and 69, recip- 25rocable through the table and provided at the upper ends thereof withthe finger bars 70 and 71, which extend across the full width of thefinger-board.- The lower ends of the rods 68 and 69 pass through thelower partition 72 of the table or machine frame to be guidedtherethrough and are surrounded by the coiled springs 73 and 7 reactingat one end a 'ainst the stationary bosses 75 and at the other endagainst the collars 7 6 and 77 3 suitably secured to said rods. Thecross arm 78, which isprovided at the ends thereof with the bores 79 and80 through the rods 68 and 69 are adapted to slide, is located immediately above the collars 76 and 77 and is connected by the link 81-to the finger operated lever 82 pivotally mounted to the table ormachine frame at 83. Surroundingthe contact plungers 59 and 60 arelocated the sleeves 8%, 85, 86 and 87 whichmay be made 5 of any suitablenonconducting material, the spring contacts 61 and 62 being secured tothe sleeves 8 1 and by any suitable means, such as screws. I The shankportions 88] and 89' of the 00 spring contacts may be in the form ofbusbars extending the full length of the switch board and respectivelyconnected to the leads 90 and 91from the electrical feed wires 92 and93, the corresponding-shank of the 55 contact springs of the additionalswitches at the end of the switch-board being both connected to thelead. 90; V -Upon the table 24 and opposite each of the finger keys 419and 50, are disposed col- 6O ored lights 94 and 95, those adjacent tothe keys 49 being of one color, in this case, red, and those disposedadjacent to the keys 50 being of another color,"in this case, green.

The electric wire system utilized for car- 65 rying out the operation ofthis invention is may be used is that of a voltage of six volts betweenthe wires 92 and 93, as well as, between the wires 93 and 96 and avoltage of twelve volts between the wires 92 and 96. 75

This system isuseful where it is desired to operate electro-magnets invarious combinations, that is, where one or more are thrown in circuitin series. Where one pair of electro-magnets (see Fig. 3) only isincluded in 0 a circuit, the latter may be made from the wire 93 to wire96 between which there is a voltage of six volts, which is sufiicient tooperatively energize a single pair of electromagnets, while on the otherhand, when it is 85 desired to include in a circuit two pairs ofelectro-magnet in series this circuit should be made from the wire 92 towire 96 between which there is a potential of twelve volts, which isample to effectively energize 9'0 said electro-magnets.

The red lights are connected in a closed shunt with the circuits of theelectro-magnets 19, 20, 21 and 22 and are used to indicate that theelectro-magnets, 19and 21 or 20 and 22, controlling the correspondingpunches of each head, are in series and are energized and that thecorresponding perforations will be made in both cards 33 and 34. Thegreen lights are connected in an open shunt circuit with the circuits ofthe electro-magnets 19 or 20 only and, therefore, indicate which of theelectroqnagnets 19 or 20 is'in circuit and energized and that thecorresponding perforations will be made in the card 33- only. This shuntcircuit leads through the contacts 97, 98, 99 and 100 or 101, 102, 103'and 104, as the case may be, of which the contacts 97, 99, 101, 103 aremounted upon thelocking rods 11, 13, 12 1 10 and 14 respectively andmovable therewith, toward or from the stationary contacts 98, 100, 1 02and 104 fixed to the table 2%.

The contacts 97,, 98, 101 and 102 are nor- 7 mally out of contact andthe contacts 99, 5 100, 103 and 104 are normally in contact. Whenever acircuit isclosed to operate any of-the punches of head 1 the lockingrods therein will carry a contact 97 or 101 to the stationary contact 98or 102 to thereby close the circuit, the other contacts remaining intheir normally closed position, and the corresponding green lightindicates the particular holes punched. If however, a circuit is closedto operate any of the corresponding punches in both heads 1 and 2,notwithstanding the fact that the contacts 97, 98, 101 and 102 willoperate as described above, the contacts, 99, 100, 103 and 104, however,will separate and this circuit broken, since the locking rods in head 2are caused to move into locking position thereby carrying the contacts100 and 103 away from the stationary contacts 99 and 104. This preventsthe lighting of the green lights accordingly.

' Inasmuch as the red lights are in shunt with the energizing circuitsof the electro-mag: nets they serve to indicate in the manner heretoforestated.

From the above description, it is apparent that when one of the keys, asfor example 49, is depressed to the dotted line position shown in Fig.2, the cross bar 55 is caused to turn about the shaft 56 and the contactplunger 59 moved downwardly through the sleeve 86 into the gap betweenthe spring contact 61 to engage therewith whereby an electrical circuitis closed. Operation of a key will similarly swing a cross bar about theshaft 56 in the opposite direction and close another circuit by movementof another plunger 66 in contact with the other spring contacts 62.Those first mentioned were on the side of the board termed the red sideand those last mentioned, on the side of the board termed the greenside.

After a number of keys on either or both sides of the finger board havebeen operated to close the circuits in the manner above described andthe punching apparatus has been operated, and in the event it is desiredto return all of the cross bars 55 to the horizontal position shown inFig. 2 thereby breaking all of the circuits the operator presses downupon the lever 82 thereby causing the link 81 and the cross arm 78 tobe'lowered. The movement of the cross arm 7 8 is thereby imparted to therods 68 and 69 through the collars 76 and 77 fixed thereto, and finallyto the horizontal rods 66 and 67 which come in contact with the upperedges of the cross bars and 65. This downward movement of the horizontalbars will bring the cross bars to the horizontal or neutral position.If, however, it is only desired to swing the cross bars of one side ofthe finger board to neutral position to break the circuits of one set ofelectro-magnets and to repeat the operation of those on the other side,the operator will not in that case oper ate the lever 82, but will, forexample, press down the finger bar 70, thereby bringing the horizontalbar 66 into contact with the cross bars 55 and 65 which have beenoperated to close the circuits on the red side, the other cross barswhich are connected to the plungers closing the circuits on the greenside not being affected thereby. This operation is possible by reason ofthe fact that as the finger bar is depressed and the rods 68 securedthereto are lowered, the collars 76 will separate from the end of thecross arm 78 and compress the coil springs 73 without any effect uponthe cross arm and the other members, 71, 77, 69 and 74.

Fig.1 is referred to as'showing, in a diagrammatic disposition, thedistribution of the electro-magnets in respect to the punch ingplungers, the electric wiring diagram and also a plan view of the fingerkeyboard or switchboard. It has been deemed only necessary to show thewiring diagram for the circuits controlling the first and secondpunching plungers of each head, as well as the wiring for the signalsfor the same, and also the wiring of the circuits controlling the largepunching plungers for punching the peg holes. The wiring for the othercircuits follow the same plan and their illustration is deemedunnecessary, the leading ends of these circuits merely being shown. Intracing out the circuit for the first punch of both heads, the operatordepresses the first key 49 of the set upon the red side of the key-boardand closesthe circuit leading from the feed wire 92 to the busbar 105,spring contacts 61, contact plunger 59, the wires 106 and 107,electroanagnets 21, wire 109, to theelectro-magnets 19, wire 110 andwire 111 to the feed line 96. One of the red lights 94, corresponding tothis circuit is connected in shunt therewith, across the wires 106 and109 leading to and from the electro-magnet 20, by the wires 112 and 113.In following the circuit for the first plunger upon the head 1, only,the operator depresses'the key 50 of the set upon the green side of thefinger key-board and closes the circuit leading from the feed wire 93,to the bus-bar 114, spring contacts 62, contact plunger 60, wires 113and 109, electro-magnets 19, wires 110 and 111 to the feed line 96. Thegreen light circuit corresponding to this operation leads from thebus-bar 114 to the light 95 and thence to the wires 117 and 118 to themovable contact 99 mounted upon one of the locking rods 13, stationarycontact 100, wire 119, movable contact 97 mounted upon one of thelocking rods 11, stationary contact 98, wires 120, 110, and 111 to feedwire 96. From the above, it will be noted that in the case of operatingthe circuit from the red side of the finger board, the electro-magnets20, corresponding to the first punch hole on the head 2, as well as theelectromagnets 19 corresponding to the first hole on the punch head 1are in circuit in series and are both operated whereby the firstplungers of both heads are locked so as to perforate the first hole of arow in each of the cards 33 and 34. In the case of closing the firstcircuit on the green side of the finger board, the corresponding redcircuit cannot be closed, but the green circuit is closed through theelectro-magnets 19 of the first punch of the head 1 only, therebypunching the first hole of a row in the card 33. The other circuits arecontrolled on both sides of the finger boards in exactly the same manneras described above. For the purpose of operating the large punchiplungers for the peg perforations, the ad itional switch operatingmeans, provided at the end of the switch board is operated upon eitherside of the board in a manner similar to operating the other circuitclosing means described above. In this case the circuit leads from thefeed wire 92, to wire*90, to either bus-bar 105 or 114, through eitherplunger contact switches 121 and 1.22., wire 123, electro-magnets 45,wire 124, electro-magnets46,

wires 125 and 111 to feed line 96. This cir-' cuitclosing means isoperated only at intervals occurring between thepatterns upon the cards,and it is optional as to which of the switches 122 is operated.

For the purpose of directing the operator in the manner of pressing thefinger keys 49 and 50 to produce a desired pattern, a chart has beencomposed from which the combined -space indicating no operation of anykey.

The vertical columns are numbered from 1 to 16, corresponding tothe'first to the sixteenth punch holes in both heads 1 and 2, as well asto the first to the sixteenth finger keys of each set on the'fingerboard. The horizontal rows represent cards, the first row of holes forthe first set of cards (here a pair) being indicated in the firstsection of the left hand side of the chart as shown in Fig. 1. Thesecond row of holes being represented by the first horizontal row inthesecond section of the chart and the third row of holes represented bythe first horizontal row in the third section, and so on indefinitelyfor the number of rows that may 7 occur in or be chosen for acard. Afterthe peg holes are punched and the card strip moved a suflicientdistance, for starting a design upon a second set v of cards the secondhorizontal row of thechart is read from left to right, each section insaid row representing as indicated above, a row of holes in the cards.

For example, in reading the chart shown,

theoperator will for punching the first rowof holes for the first pairof cards, press th keys from 1 to 16 as follows: Red, 1, '2, 4 and 6,green 7, red 10,12,15,16;second row green 1 red 2, green 3, 5, red 6, 7,8, 9, green 10, red 11, 13, green 14, 15, red 16, and so on for. thesucceeding rows, until the length of a set of cards is completed. Inperforating the second set, of cards, the operator mounted upon thetable 1124.

reads upon the. second horizontal row from left to right, similarly tothe manner indicated above. l

In addition to the above means it frequently occurs that a patternof-more or. less uniform orsymmetrical design is to be controlled, andin order to facilitate operating the circuits therefor and also to savetime, I haveprovided at each side of the finger keyboard supplementarycircuit closing means, as is shown in the simpler form in Figs. 2, 5 and6 and in a more elaborate form in Figs; 9 and'lO.

In the form shown in Figs. 2,5 and 6 the supplementary circuit closingmeans comprise pivoted supports 126 and 127 The upper ends of thesupports carry laterally slotte'd beams 128 and 129 in the slots ofwhich slidablyrepose the comb bars 130 and 1310f electrically conducting.nretal, suchras brass, copper, or the like. These comb-bars areprovided with lateral teeth like :contact' points 132 and 133'adaptedtojsuccessively contact with the shanks 61' andta of the springcontacts 61 and 62; respectively as the combba'rs are moved;longitudinallyiin the grooves or slots of the beams 128 and .129-

These contact points are distributed along the comb-bars in certainspaced; relation-determinedupon the relation of the circuits to becontrolled. In the form shown in: Figs. 5 and 7, the contact points arearranged to contact with thefirst, fourth, seventh, tenth, thirteenthand'sixteenth shanks 61 and 62, in the first circuit closing position of:this particular comb-bar. In the second circuit closing position thisform of comb-bar, closes the circuits forthe seoond, fifth, eighth,eleventh and fourteenth shanks 61" and 62?, and so on indefinitely.

In Fig. 8 the Contact points are shown as arranged in the order to closethe circuits of the first, seventh and-thirteenth shanks in the firstcircuit closing position; thesecond, eighth and fourteenth shanks inthe'second position; the third, ninth a'nd fifteenth in the thirdposition, and so forth), The operations described will produce a patterneffect termed a twill; and shown,.for the comb- 'bar of Fig. 8, in thedesign chart of'Fig. 11, the symbols w showing the form of twillproduced. If. in operating these combbars,

that on the red side ,of'the switch-board be successively moved in thedirection from the first to the sixteenth shanks 61and that on the greenside be simultaneously moved from the sixteenth to the firstshanks 62',the combined pattern effect will be of a honey-comb.design as is shownin the combined arrangement of the symbols w and 0,in-the design chartshown in Fig. .11.

The shanks 61 and 62? asis clearly shown in Figs. 5 and 9, are embeddedin the, insulating material of the key-boardso that the faces of boththe shank pieces and the insucomb-bars so that the contact points willlie between the shanks 61 or 62, or even beyond the same at the end ofthe switch-board, has the effect of opening all of the circuits of thecomb-bars so positioned.

The springs 134: and 135 are secured to an end thereof to the supports126 and 127 and at the other end to fixed uprights 186 and 137 rigidlysecured to the table24c. These springs serve the purpose of constantlyurging the beams and comb-bars'toward the shanks 61 and 62so that thecontact points thereof shall bear with the pressure requisite to make agood electrical contact between the points and the shanks, as the barsare successively moved, in the manner described above. a d

In the beamsare also provided recesses in which are disposed springs 138and 139 the ends of which resiliently bearagainst the rear edges of thecomb-bars 130 and 131 and the centers of which are suitablysecuredtothebeams as by screws140 and 141. These springs also aid inpressing the combbar-contact points against the shanks 61 and '62,{andalso compensates for variations in the widths o'f'the bars used aswell as for wear thereof.

The bars are also-each provided with perforations or depressions 1 12with which spring detent means 143 ofany suitable type may cooperate totemporarily lockthe bars in their successive positions but not with suchengagement astoprevent movement of the bars by hand. V i

At the end of the beams 128 and 129 are provided contact plates 144 and14-5 adapted to engage with the rear edges of the combbars, wherebyelectrical current leading in through the leads 1-16 and 147 may beconducted tothe combbars 130- and 131 for the purposes mentioned above.I

In operation, the operator -lowers the beams 128 and 129 about pivots'otthe supports and places in the slots thereof a set of comb-bars 130 and131 and the beams are then permittedto swing up to position,

under the influence ofthe springs 134; and 135, where the contact pointsof the 'coml bars are pressed against the surface in which the shankcontacts are embedded. The

bars may then bemoved longitudinally in the beam slots to present thecontact points to the shankswhereby certain related circuits maybeclosed. If the type of bar shown in Fig; She used, the first, seventhand thirteenth circuits, on the red side of the switchboard, will beclosed as reprcsented by the symobls w in the lower row of the designchart shown in Fig. 11. On

moving the bar to the next position the second, eighth and fourteenthcircuits will be closed, and thence accordingly for the full range ofmovement of the bars. This will effect a twill as represented by thesymbols as only. If, however, at the same time the bars on the greenside be operated in the reverse direction, as from the sixteenth to thefirst circuits, at the same time as the red side bar is operated, thecombined effect will be that shown by the arrangement of the symbols 00and 0 in Fig. 11, which'is called a honey-comb pattern. If, however, thecomb-bar tor the green side he started at an advanced shank contact, asfor example at the fourth rather than the first, when the comb-bar forthe red side is started at the first shank contact, and both are movedin the same direction, the combined effect obtained is shown in thechart of Fig. 12, which is a twill pattern. It on the other hand thecomb-bars on the red and green sides are advanced at different rates thepattern lines of one will cross the other and, therefore, produce asatin effect as shown in Fig. 13.

The charts in Figs. 11, 12 and 13 are shown more for illustrating thetype of design or pattern ett'ect obtained rather than the chart fromwhich the operator reads. The chart from which the operator con-' trolsthe operation of the comb-bars is in fact similar to that shown in Fig.at but the designs shown in Figs. 11, 12 and 13 are arranged to moreclearly shoe the resultant relation of the design points controlled.

The device shown in Figs. 9 and 10 is in all respects the same as thatshown in Figs. 5 and 6 with the exception that a plurality ot=c01nb-bars180 and 131 may be plaierl in eachbeam and the beams are provided withmechanical means whereby the bars may be moved definite distances in onedirection or the other by the simple manual movement of said means.

These beams are, therefore, provided with longitudinal slide ways 148and 119 in which are adapted to slide the slide-bars 150 and 151. arepivotally attached tl e spring pressed pawl-hooks 152 and 153 adapted toengage with the teeth 154C and 155 provided upon the rear edges of thecomb-bars. The other ends of the slide bars are provided with fingerbuttons 156 and 157 projecting upwardly above the top of the beams.Springs 158 and 159 are nested in the ends of the slide-ways toroperation agalnst the slide bars to return the same to initial position,

when the same have been manually operated as indicated above.

When it is desired to reverse the movement of the comb-bars, thepawl-hooks 1-32- and 153 may be thrown out of engagement At the freeends of the latter by the arm' 160 or 161 of the release levers 162 or163 as the latter are manually moved by the handle portions 164; or 165.Detent projections 166 carried on each lever are adapted to engagedepressions 167 on the beams for the purpose of holding the levers intheir alternate positions. When the pawlhooks are thus dis-engaged fromthe bars at vone end thereof, the release lever at the other end may beoperated to permit the reengagement of the pawl-hooks 152 and 153 withthe teeth 151' and 155 and manual manipulation of the finger buttons156" and 157 will be effective to move the bars as in the firstoperation described except in the reverse direction.

It will be notedthat the arms 160 and 161 of the release levers areprovided with detent hooks 168 and 169,;engageable with the teeth 154,155, 15 1 and 155 of thecom b bars to act as detent pawls therefor. Whenthe release levers are operated tojdisengage the pawl-hooks these detenthooks will also be simultaneously disengaged ,7 1 The circuit jleads -116 andf1i7 are connected to the contact plates 1451: and 1 15 which aresuitablysecured tojtheend of the insulating material of the switch-boardand which also engages with the front edges of the shanks of, thecomb-bars, as is clearly shown in Fig. 9. g V

The operation of this form of supplementary circuit closingmeans issimilar to that shown in Figs. 5 and 6 and described above withtheexception that the movements of the comb-bars are accomplished I bymanually movin the finger buttons 1 56, 157, 156- and 15 The amount ofmovement is half of the distance between the shanks of the springcontacts, so that two movements of a finger button will be required tomove a contact point on a combbar from one of the shank contacts to thenext. A single movement will, obviously, carry the contact points toinsulated points between the shank contacts thus opening the circuits.In;order'that the'finge'r buttons may have theproper amount of movementstop-pins 170, 171,1?0 and 171. are driven into the beams 128 and 129 atproper points to limit such movement. I I

The leads to the contact plates 14A and 144:- .on the red. sideareconnectedto the feed wire 92, while the leads to the contact plates 14:5and145' on the green side are connectedtoithe feed wire 93. The;circuits on the other side of the shank contacts are completed inexactly the same manneras hereinbefore' described in connection with thewiring diagram shown in Fig. 1.

Where, however, the design or thepattern :to be produced involvestheoperation of nearly all of thepunches, a few holes only in each set ofcards being omitted, it has been found? that the punching operation mayclaim as new and desire to secure by be carried out with a great savingof time and with greater facility by first closing all of the circuitson one side or the other of the switch board by depressing the fingerbars or 71 to the full extent as shown in dotted lines in Fig. 2 wherebyall of the switches onthe red or green 7 sides respectively are closed.For the purpose of preventing certain of the punches on a side fromoperating it is then onlynecessary to open the corresponding individualswitches on the red or green side by pressing the keys 50 or 49respectively on the opposite side to chines for the manufacture oflaces,nettings and similar articles, are also as fully adapted for use withany machine, controlled by jacquard cards, and used for the manufactureof other articles, such as carpets, upholstery materials and similarproducts.

By the above described invention it has become possible to perforatecards with a larger number of holes than heretofore and to alsoperforate similar. patterns simultaneously in a plurality of cards, andtherefore, whilevone formor embodiment of the invention hasbeendisclosed it is to be understood'that the invention is not limitedparticularly thereto, but comprehends also the idea of perforating anynumber of holes simultaneously in an indefinite number of cards as wellas the perforating of additional holes in any of the cards as may beselected, andit is to be further understood that many changes in thisinvention are fully contemplated as may be within the aim and the spiritof the present invention and within the scope of the appended claims.
